Title (EN) PROCESS FOR THE SIMULTANEOUS ELIMINATION OF TOXIC MATTER CONTAINED IN FLUE GAS AND REACTOR FOR IMPLEMENTING THE PROCESS
(FR) PROCEDE D'ELIMINATION SIMULTANEE DE MATIERES TOXIQUES CONTENUES DANS DES GAZ DE FUMEE ET REACTEUR POUR L'APPLICATION DU PROCEDE
Abstract:
(EN) According to this process multiple and stoechiometrically determined quantities of a fine-grain solid additive which combines with toxic matter are introduced in the flue gas downstream of the heating installation. The additive is partly transformed with the toxic matter contained in the flue gas and the direction of flow of the additive-laden flue gas changes several times in the reactor; it is then precipitated and after this the remaining additive is separated from the flue gas by a filter. The process is characterized by the fact that a certain proportion of the additive is separated from the flue gas flow and the reactor or downstream of the latter, but in any case before the filter, and it is reintroduced after fragmentation into the flue gas flow between the boiler and reactor or after its entry into the reactor. This process enables better use to be made of the additive and to eliminate more toxic matter contained in the flue gas.
(FR) Selon ce procédé, des quantités multiples, stoechiométriquement déterminées, d'un additif solide à grains fins se liant aux matières toxiques sont introduites dans le gaz de fumée en aval de l'installation de chauffe. L'additif est partiellement transformé avec les matières toxiques contenues dans le gaz de fumée pendant que le sens d'écoulement du gaz de fumée chargé d'additif se modifie plusieurs fois dans le réacteur, à nouveau précipité, puis l'additif restant est séparé du gaz de fumée par un filtre. Le procédé se caractérise par le fait que l'on sépare une certaine proportion de l'additif du courant de gaz de fumée dans le réacteur ou en aval de celui-ci, mais en tout cas avant le filtre, et qu'on le réintroduit, après fragmentation, dans le courant de gaz de fumée entre la chaudière et le réacteur ou après son entrée dans le réacteur. Ce procédé permet de mieux utiliser l'additif et d'éliminer davantage de matières toxiques contenues dans le gaz de fumée.
